Before opening How Christianity Changed the World, it is important to understand what kind of book this is and what it is not. Alvin J. Schmidt does not write a devotional work meant to stir emotion, nor does he offer a sermon or a theological treatise focused on doctrine alone. Instead, this book is a historical examination of how Christianity, as a worldview rooted in the teachings of Jesus Christ, reshaped civilizations in concrete and measurable ways. Approaching the book with the right expectations will help readers grasp its significance and avoid common misunderstandings.

First, readers should understand that Schmidt writes as a historian and sociologist. His arguments are grounded in documented historical facts, primary sources, and comparisons between Christian and pre-Christian societies. The book does not assume that the reader already believes Christianity is true. Rather, it examines what happened in history after Christian ideas took root. This makes the book especially valuable for readers interested in apologetics, cultural history, and the intellectual defense of Christianity’s impact on the world.

Second, this book directly challenges the modern assumption that Christianity hindered progress or suppressed human freedom. Many contemporary narratives portray Christian influence as anti-science, oppressive, or socially regressive. Schmidt confronts these claims by tracing the origins of hospitals, universities, human rights, scientific inquiry, charity, and the value of human life. Before reading, it helps to recognize that the book will unsettle widely accepted cultural myths and replace them with carefully supported historical evidence.

Readers should be prepared for uncomfortable contrasts. Schmidt does not romanticize ancient civilizations. He describes in detail practices such as infanticide, slavery, sexual exploitation, and the devaluation of women that were common and socially accepted before Christian moral teaching challenged them. These sections are not written for shock value, but to show how radically Christian beliefs about human dignity transformed societies over time. Reading with honesty and patience is essential, especially when these realities clash with idealized views of the ancient world.

It is also helpful to understand that Schmidt distinguishes between Christianity as taught by Christ and Christianity as imperfectly practiced by individuals or institutions. The book does not deny historical failures, abuses, or hypocrisy among Christians. Instead, it asks a different question: what moral and social changes occurred when biblical ideas were taken seriously. Keeping this distinction in mind prevents readers from dismissing the book based on objections related to human failure rather than core Christian principles.

Finally, If you are planning to read the book, you should approach this book with a willingness to think historically rather than emotionally. Schmidt builds cumulative arguments. One chapter alone may not feel decisive, but taken together, the evidence forms a compelling picture of Christianity’s transformative influence. This is a book that rewards slow reading, reflection, and note taking.

Reading How Christianity Changed the World with these expectations will prepare you to engage its arguments fairly and thoughtfully. Whether one reads it as a believer, a skeptic, or a student of history, the book invites serious consideration of a question that continues to shape global culture: what actually happens when the teachings of Jesus Christ take root in human society.
